Investment casting with duplex alloys can achieve specialized characteristics that are required or desirable for a variety of applications. Duplex alloys consist of austenitic (non-magnetic) and ferritic (magnetic) stainless steels in varying proportions to achieve desired properties. Changing the proportions and including other additives enables the foundry to fine-tune the resulting alloy to have increased strength, be more corrosion resistant, weld better, perform at cold temperatures, and have other attributes. An experienced metallurgist can produce the best duplex alloy for each specific need.
